MCP Proxy

mcp-proxy is a lightweight bridge that converts between MCP transports, letting you run a server on stdio and expose it over Streamable HTTP (SSE) or do the reverse. This enables existing desktop-style MCP servers to be reused by web services and IDEs that prefer HTTP, without modifying the server. The tool can multiplex multiple named STDIO servers behind one proxy instance, simplifying fleet deployments or local development with many tools. It ships prebuilt artifacts and a Homebrew formula for quick install on macOS and Linux, with container images published for broader environments. Releases show steady improvements focused on developer experience and operational flexibility. Overall, it lowers the friction of composing diverse MCP tools into a single reachable endpoint.

Features

Facilitates communication between SSE clients and stdio MCP servers
Provides a command-line interface for easy setup
Includes a Node.js SDK with utilities for proxy creation
Enables CORS by default for cross-origin requests
Simplifies integration of stdio MCP servers with SSE clients
